microRNA miRNA and small interfering RNA siRNA)use a similar process and proteins to regulate gene expression.Which of the following is more commonly associated with the miRNA pathway?
A)The protein AGO is found in the miRNA pathway but not the siRNA pathway.
B)The protein complex RISC is found in the miRNA pathway but not the siRNA pathway.
C)The protein Drosha is found in the miRNA pathway but not the siRNA pathway.
D)In animals,the miRNA pathway usually leads to mRNA degradation,and in the siRNA pathway,the mRNA is not degraded.
E)The protein Dicer is found in the miRNA pathway but not the siRNA pathway.

The protein Drosha is specifically involved in the miRNA pathway for the initial processing of miRNAs in the nucleus, whereas the siRNA pathway does not involve Drosha. Both miRNA and siRNA pathways involve AGO proteins, RISC complex, and Dicer, and can lead to mRNA degradation.
